Engineering Selection Recommendations

Primary Substitute (Same Manufacturer): The 7X-16.000MBE-T from TXC CORPORATION is the direct successor to the TC-16.000MBE-T. Both parts share identical electrical specifications and physical footprint. The 7X series maintains Active product status and is available in Tape & Reel packaging. Current supply is reduced to 20mA, and height is increased to 0.043" (1.10mm), both within acceptable mechanical tolerances for standard PCB assembly.

Alternative Substitutes (Active Status): LFSPXO025494 (IQD Frequency Products), OXETGLJANF-16.000000 (Taitien), and SXO32C3A481-16.000M (Suntsu Electronics, Inc.) are all Active products meeting all mandatory electrical parameters. These alternatives offer reduced current consumption (7mA to 10mA) compared to the original part. Height variations range from 0.043" to 0.047", requiring PCB layout verification for clearance compatibility.

Compliance Considerations: LFSPXO025494 and OXETGLJANF-16.000000 carry ROHS3 Compliant certification. SXO32C3A481-16.000M carries ROHS3 Compliant certification. All substitute parts maintain REACH Unaffected status where specified. The original TC-16.000MBE-T carries RoHS status as Compliant.

Frequently Asked Questions (FAQ)

Q: Can the TC-16.000MBE-T be directly replaced with the 7X-16.000MBE-T?

A: Yes. Both parts are manufactured by TXC CORPORATION and share identical electrical specifications (16 MHz, 3.3V, CMOS output, ±50ppm stability, -40°C ~ 85°C operating range). Physical dimensions are identical at 0.126" L x 0.098" W. The height difference (0.031" vs 0.043") must be verified against PCB clearance requirements.

Q: What is the primary difference between MEMS and Crystal-based oscillators in this application?

A: The TC-16.000MBE-T uses MEMS resonator technology, while substitute parts 7X-16.000MBE-T, LFSPXO025494, OXETGLJANF-16.000000, and SXO32C3A481-16.000M use Crystal resonators. Both technologies deliver identical electrical performance at 16 MHz with ±50ppm stability. Crystal-based alternatives are currently in Active production status.

Q: Which substitute offers the lowest power consumption?

A: LFSPXO025494 from IQD Frequency Products operates at 7mA maximum supply current, compared to 25mA for the original TC-16.000MBE-T and 20mA for the 7X-16.000MBE-T. OXETGLJANF-16.000000 and SXO32C3A481-16.000M both operate at 10mA.

Q: Are all substitute parts available in Tape & Reel packaging?

A: 7X-16.000MBE-T, LFSPXO025494, and OXETGLJANF-16.000000 are available in Tape & Reel packaging. SXO32C3A481-16.000M is supplied in Bulk packaging. Packaging selection depends on production volume and assembly line requirements.

Q: Do all substitute parts meet RoHS compliance?

A: LFSPXO025494, OXETGLJANF-16.000000, and SXO32C3A481-16.000M carry ROHS3 Compliant certification. The 7X-16.000MBE-T carries RoHS Compliant status. Verify specific RoHS revision requirements for your application.

Q: What is the maximum height difference among substitute parts?

A: The original TC-16.000MBE-T has a seated height of 0.031" (0.80mm). Substitute parts range from 0.043" (1.10mm) to 0.047" (1.20mm). This 0.016" to 0.020" increase requires PCB layout verification for component clearance and solder reflow profile compatibility.

Q: Can substitute parts be used interchangeably on existing PCBs?

A: All substitute parts maintain identical footprint dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and 4-SMD, No Lead package configuration. Height variations must be evaluated against PCB clearance, neighboring component placement, and solder reflow thermal profiles.
